%description
Fits linear varying coefficient (VC) models, which assert a linear
relationship between an outcome and several covariates but allow that
relationship (i.e., the coefficients or slopes in the linear regression)
to change as functions of additional variables known as effect modifiers,
by approximating the coefficient functions with Bayesian Additive
Regression Trees. Implements a Metropolis-within-Gibbs sampler to simulate
draws from the posterior over coefficient function evaluations. VC models
with independent observations or repeated observations can be fit. For
more details see Deshpande et al. (2024) <doi:10.1214/24-BA1470>.
